Application filed i'uly 5, 1912. Serial No. 707,852.

1 0 all whom "it may concern Be it known that l, .ziuoi the tone therefrom.

The principal objects oil my invention are to provide a inuteu'hich may be readily as seinl'iled in operative relati n to exist-inf; wind instruiners and adjusted to check or subdue the to v therefrom without puttin "he instrument out of tune.

In the drawings, forming a art .i this specification: Figure .l a le elevation of the device embodying in is a central longitudinal device as disclosed in F end elevation of the tlQ'VlO'e as di Fig. 1. Fig. 4t a view partly in elevation and partly in section shewine the application of my device to a wind in Similar characters refer to similar parts throughout the views.

A shell 1, preferably frusto conical in shape, open at. both ends, is adapttal to be disposed stationarily in the tone emitting conduit of a Wind instrument. in Fig. this shell. shown sposed in the bell. L a cornct 3. In order to adapt the device to be readily disposed in operative relation to exist-in; instruments, or removed therefrom, a plurality of strips 4, of rubber, leather or the like having a high eoetiicicnt of friction, is secured longitudinally and exteriorly of said shell, so that a slight inward pressure upon inserting the shell into the horn bell,

brings the strips in close contact with the surface of such bell. At its larger end the shell 1 has a cylindrical extension 5 which has a telescopic engagement with the shell The other end of the shell. 1 provided with an internal annular "flange, 7 by which a tube 8 is telescopically carried, and a 0nd tube 9 may be telescopical carried by the tube 8, to render the device capable of a wide range of adjustment. The end of cy: lindrical shell 6 is provided with a cap 10, closing one end, and telescopically carried by the shell. All the parts movable with re spect to each other are in such frictional en gagement as to normally retain an adjusted position which is attained manually.

In use, the -various telescopic members are moved to extend or contract the device until they are so dispo ed that the mute, inserted into the tone emitting coi'iduit of the Wind inslrnn'lent, checks or subdues the tone Withcut putting; the instrument: out of tune, that is, the same note is sounded by manipulation of the same key, plungercr the like, on the instrument as it sounded by manipulation of the same keys, without the. mute inserted into the conduit, but the mute subdues the tone.

it. ivill of-course be understood that varis ous modifications of my invention may be employed Without departing from the spirit of my invention.

1. it col-net mute comprisino'in combination, frnsto-conical shell having an extension at its larger end, a tube telescopically carried by said shell at itssmaller end, a cylindrical shell telescopically carried by said extension of said shell, and a cap telescopically carried by said cylindrical shell at its end opposite its engagement with the said extension of said shell, su 'stantially as and for the purpose set forth.

fl. cornet mute comprising in combination, a frusto-conieal shell having an extension at its larger end, frictional elements posst sing a high coeilieient of friction carried by said shell on the'exterior thereof for ene'agenientwith the surface of the tone emitting conduit of the instrument, to retain saidshell stationarily with said conduit, a tube telescopically carried by said shell at its smaller end, a cylindrical shell telescopically carried by said extension of said shell, and a cap telescopically carried by said cylindrical shell at its end opposite its engagement with said extension of said shell, substantially as and for the purpose set forth.

2-,. In a cor-net mute, the combination of a frusto conical shell having an extension at its larger end, a tube telescopically carried by said shell at its smaller end, a cylindrical shell telescopically carried by said extension of said shell, a cap telescopically carried by said cylindrical shell at its end opposite its engagement with said extension of said shell, and a second tube telescopically carried by said first mentioned tube, substantially as and for the purpose set forth.

4, A comet mute comprising in combination, a frusto conical shell having an extension at its larger end, frictional elements I possessing a high eoeilicient of friction car ried by said shell for engagement with the surface of the tone emitting conduit of the instrument, to retain said shell stationnrily within said conduit, a tube telescopically carried by said shell at its snmllerend, at cylindrical shell telescopically carried by said extension of said shell, a cap teleseopieally carried by said cylindrical shell at its encl opposite its engagement with the said extension oi said shell, and a second tube telescopically carried by said first mentioned lube,substantially as and for the pun pose forth.
